...And this may be different to the limit of government jurisdiction. In
the UK, local authorities' jurisdiction goes (normally) to MLWS (mean
low water - spring tides), which is beyond the MHWS coastline. Why am I
saying this? Please don't use the same way in both the coastline and the
admin boundary, unless you are absolutely sure they coincide by
definition (not by coincidence).
